CAUTION
• To avoid electrical shock and to prevent damage to the
furnace, air conditioner, and thermostat, disconnect the power
supply before installing or servicing the thermostat or any part
of the system. This can be done at the circuit breaker.
• Do not reconnect electricity until work is complete.
• Do not short (jumper) across electric terminals at the control
on the furnace or air conditioner to test the system. This can
damage the thermostat.
• Your thermostat is a precise instrument. Handle it with care.
• All wiring must conform to local codes and ordinances.
• This thermostat is designed for use with 4AA alkaline batteries
and/or 24- volt AC C wire (or a 12- 24 AC or DC source) and
